Technology-schmology. It's speed I'm interested in. I use app_scroll
in another application that will view the same images without any
problems, and the scrolling is *MUCH* slower if you have any reasonably
sized viewing window - like 1000 x 1000 pixels.

Sure app_scroll may be more reliable, but it doesn't make me happier.

And when I'm paying big $$ for applications like IDL and pricey video
cards, I expect them to work as advertized. OK, so I'm not paying - but
somebody is :-)
